Journal Article
Ensor, J., Burke, D., Kwok, C., Riley, R., Holmvang, L., Mamas, M., Sirker, A., Potts, J., Martinez, S., Gulati, M., Alasnag, M., & Rashid, M. (2018). Persistent sex disparities in clinical outcomes with percutaneous coronary intervention: Insights from 6.6 million PCI precedures in the United States. PloS one, https://doi.org/10.1371/journal.pone.0203325

Background
Prior studies have reported inconsistencies in the baseline risk profile, comorbidity burden and their association with clinical outcomes in women compared to men. More importantly, there is limited data around the sex differences and how...
